General information

Frasera ackermanae is known only from Uinta County, Utah where it is found in mixed Utah juniper, mountain brush and deseretic scrub communities. Ackerman Green Gentian has four white petals per flower which bloom above a hairless, leafy plant with opposite folded leaves. The flower petals have a purple spot and a gland with white hairs on its margin. These features combined make this plant quite unique and maybe easier to spot when you are searching for it. This species is still incredibly rare and mostly known from a few populations nearby the type locality where it was first described in 2007 and a more recent discovery to the east observed in 2021.
